Inclusionary zoning, Part 1
In many previous posts I’ve alluded favorably to the concept of inclusionary zoning. As one of the two truly innovative affordable housing resources invented in the last thirty years (the other being investment tax credits, the purest and most effective expression of soft equity), it deserves its own exposition, using as a case study a recent laudatory New York Times article on New York City’s multi-pronged efforts to use inclusionary zoning and its ilk as production drivers.
It seems counterintuitive, but the luxury real estate market is helping to build housing for low- and moderate-income people.

A.What it is
Conceptually, inclusionary zoning is a trade of entitlement permission for affordability in kind. A parcel of land (usually
Inclusionary zoning
A metropolitan or local authority schema whereby a locality makes the following bargain with participating developers:
· Zoning approval for residential development on land within its jurisdiction. (Also includes density bonuses or other up-zoning entitlements in exchange for affordability.)
· Affordable set-aside, with some of the homes reserved as affordable according to the locality’s definition. (Percentage reservation, affordability definition and level, and permissible tenures are all customizable elements established by the locality.)
While most inclusionary zoning is a local or metropolitan initiative, in some cases it is imposed by the state, which in effect ‘crams down’ an affordability mandate on its localities by allowing developers to override local zoning restrictions if they meet the state’s inclusionary-zoning affordability requirements. The granddaddy of state-level inclusionary zoning statutes is
In its basic bargain inclusionary zoning is kin to linkage, Community Preservation Trusts, redevelopment areas (RDAs), and the proposed (but not enacted) GSE half-tithing proposal. All are part of the phylum of dedicated evergreen funding streams.

B. How it works
In economic terms, inclusionary zoning is a tax upon development rights, assessed against the increase in value between (1) undeveloped and unzoned land, and (2) that same land still undeveloped but now zoned. [Zoning is destiny.]
Rather than being cash, it’s paid in-kind – taken in the form of housing affordability or ongoing price/ rent bargain. Being in-kind is not a bug, it’s a feature — and one with curious, unexpected, but meaningful benefits.
There’s a further variant: linkage, which essentially creates a secondary (resale) market in zoning permissions and affordability mandates — and because markets always clear, issuance of zoning scrip travels with breathtaking rapidity from those who have it to those who need it to build. So
Inclusionary zoning [is] one of several city programs that provide incentives for market-rate developers to contribute to the inventory of affordable housing. They can:
· Buy extra space for their buildings from affordable housing developers [transferable linkage — Ed.]
· Include affordable apartments in their buildings [pure inclusionary zoning — Ed.]
· Buy city-issued certificates from developers of affordable housing that allow them to pay lower property taxes. [Transferable real estate tax abatement linkage — Ed.]

By definition, inclusionary zoning operates in jurisdictions that require approval before development. Beyond that legal requirement, which applies almost everywhere in

… and where it doesn’t work
Inclusionary zoning doesn’t work where there is no zoning, because without zoning government never gets to the closing table.

Nor does it work when metropoli can readily expand and vacant land is amply available.

Hands up,
Nor does it work when the economy is stagnant or declining.

Sorry Butch, no point in inclusionary zoning in the Hole in the Wall
Nor when the population is declining or dispersing.

No value benefit from rezoning here
But not coincidentally, places where inclusionary zoning doesn’t work tend to have plenty of conventionally affordable housing.
Would it work in New New Orleans?
Not in Under New Orleans, because that land has negative value (it will cost more money to clear and clean than it will be worth ready for development). It will work in Over New Orleans, especially if in addition to the natural advantages those areas are designated as enterprise or redevelopment zones.
Why does it work? That’s the subject for Part 2, coming tomorrow.
